3 times (-8) times (-2)

Mathematics
1 answer:
dexar [7]2 years ago

Answer:

48

Step-by-step explanation:

Signals during a multiplication of two numbers:

They have the same signal: The multiplication is positive.

They have different signals: The multiplication is negative.

3 times (-8) times (-2)​

First 3*(-8):

Different signals, so negative. 3*8 = 24. So the answer is -24.

Then:

3*(-8)*(-2) = (-24)*(-2)

Same signal, so positive. 24*2 = 48. The answer is 48.

Bob bought a broken motor scooter, repaired it, and sold the scooter for $130. That was $50 less than 1.5 times what he paid for
FromTheMoon [43]

Answer: $120

Step-by-step explanation:

Assume the original price is x.

He sold the scooter for $130 and this was $50 less than 1.5 times what he paid for it.

Relevant formula is therefore:

1.5x - 50 = 130

1.5x = 130 + 50

x = 180/1.5

x = $120

The function models the number of accidents per 50 million miles driven as a function
sesenic [268]

Answer:

x=39, y=180

Step-by-step explanation:

f(x)=0.4x²-31.2x+788.4

For x=39 the graph reaches its lowest point.

The minimum value of y is:

x=39→y=f(39)=0.4(39)²-31.2(39)+788.4

y=f(39)=0.4(1,521)-1,216.8+788.4

y=f(39)=608.4-1,216.8+788.4

y=f(39)=180

Which value must be added to the expression x^2+12x to make it a perfect square trinomial a:6 b:36 c:72 d:144
Ksivusya [100]

The answer would be 36. Why?


Because in the equation we would need to do (x + 6)(x + 6) to get a perfect square trinomial.


And 6 * 6 is 36.


So the whole equation would be: x^2 + 12 + 36.


Hope this helped! c:
